Hydroelectricity

Zimbabwe's planned Batoka Gorge power project on the Zambezi River is expected to generate 2,400 megawatts (MW) of electricity, upward from an initial 1,600 MW, but the worsening power cuts that are being blamed on low water levels have renewed concerns about the effects of climate change on mega dams.

In the case of the Belo Monte hydroelectric dam in Brazil, the projects aimed at mitigating the social impacts have been delayed. But in other cases, infrastructure such as hospitals and water and sewage pipes could improve the image of the hydropower plants on Brazil’s Amazon rainforest rivers, turning them into a factor of effective local development.

Some argue that the sustainable use of biodiversity is the best alternative for local development in the area surrounding the enormous Belo Monte hydroelectric dam, now that the construction project is entering its final phase on the Xingú River in Brazil’s Amazon jungle.

After its victory in a nearly decade-long struggle against HidroAysén, a project that would have built five large hydroelectric dams on wilderness rivers, Chile’s Patagonia region is gearing up for a new battle: blocking a quiet attempt to build a dam on the Cuervo River.
